Class VertexImpl

java.lang.Object
  org.apache.tez.dag.app.dag.impl.VertexImpl

All Implemented Interfaces:

Comparable<Vertex>, org.apache.hadoop.yarn.event.EventHandler<VertexEvent>, Vertex

public class VertexImpl
extends Object
implements Vertex, org.apache.hadoop.yarn.event.EventHandler<VertexEvent>
